"According to the versions of the poppler packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - The JPXStream::init function in Poppler 0.78.0 and
    earlier doesn't check for negative values of stream
    length, leading to an Integer Overflow, thereby making
    it possible to allocate a large memory chunk on the
    heap, with a size controlled by an attacker, as
    demonstrated by pdftocairo.(CVE-2019-9959)

  - In Poppler 0.72.0, PDFDoc::setup in PDFDoc.cc allows
    attackers to cause a denial-of-service (application
    crash caused by Object.h SIGABRT, because of a wrong
    return value from PDFDoc::setup) by crafting a PDF file
    in which an xref data structure is mishandled during
    extractPDFSubtype processing.(CVE-2018-20662)

  - Poppler 0.74.0 has a heap-based buffer over-read in the
    CairoRescaleBox.cc downsample_row_box_filter
    function.(CVE-2019-9631)

  - PDFDoc::markObject in PDFDoc.cc in Poppler 0.74.0
    mishandles dict marking, leading to stack consumption
    in the function Dict::find() located at Dict.cc, which
    can (for example) be triggered by passing a crafted pdf
    file to the pdfunite binary.(CVE-2019-9903)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
